DS90UR910QSQX/NOPB Application Field and Working Principle

The DS90UR910QSQX/NOPB is an ultra-low power, low-voltage, nine-bit SERDES (serializer/deserializer) transceiver that operates from a single 2.5 V supply. This device is part of the DS90UR910Q family of universal serializers/deserializers (SERDES) that provides the building blocks for multiple serial digital data links for the point-to-point connections and on-chip peripheral interconnects. With a low operating voltage of 1.8 V with an operating range from 1.8 V to 2.5 V and only 5 mW maximum power dissipation, the DS90UR910QSQX/NOPB is designed to meet the requirements of low power applications while providing high system performance.

The DS90UR910QSQX/NOPB comprises a wide array of features that enable it to be used in multiple data interfaces. These features include a selectable low-voltage differential signaling (LVDS) compatible output, selectable data rate (64 Mbps to 3.2 Gbps), selectable high-speed LVDS capable outputs, and adjustable pre-emphasis. In addition, the device also provides various selectable multiple high-speed protocol modes, integrated equalizer, and selectable spread spectrum clocking (SSC) up to 3.2Gbps.

Application Field

The DS90UR910QSQX/NOPB is ideal for use in a variety of low-power applications including digital video transmission, external storage and memory interconnects, video over CAT-5E/6/7 applications, and HDMI cable extension. This transceiver can also be used in multiple digital multimedia streaming applications such as LCD, plasma, and projector interfaces. Finally, the DS90UR910QSQX/NOPB is suitable for use in FPD-link, HDMI with Ethernet, and other ultra-fast interconnects.

Working Principle

The DS90UR910QSQX/NOPB is an ultra-low power, low-voltage, nine-bit serializer/deserializer transceiver that supports data rates up to 3.2 Gbps and operates from a single 2.5 V supply. It features a selectable low-voltage differential signaling (LVDS) compatible output, selectable data rate (64 Mbps to 3.2 Gbps), selectable high-speed LVDS capable outputs, and adjustable pre-emphasis. In addition, the device also provides various selectable multiple high-speed protocol modes, integrated equalizer, and selectable spread spectrum clocking (SSC) up to 3.2Gbps.

The transceiver uses an LVDS compatible output to convert eight serial data bits and a frame sync signal into LVDS compatible outputs. The frame sync and data bits are sent serially, but can also be sent as two separate LVDS signals and combined with software. The adjustable pre-emphasis on the LVDS outputs can be used to reduce electromagnetic interference and increase signal integrity.

The serializer/deserializer is composed of a serial data path and a serial clock path. The serial data path consists of multiple components that provide the data-handling functions. The serial clock path contains the same components such as switches, gain elements, and limited circuits that allow the device to generate, regulate, and deliver a clock signal for the serial data path. The combination of these components allows the device to convert serial data into LVDS compatible outputs and vice versa.

The DS90UR910QSQX/NOPB is designed for low power operation, with a maximum operating voltage of 2.5V and a maximum power dissipation of 5 mW. It also features an integrated equalizer and adjustable pre-emphasis, which help to improve data integrity and reduce emitted noise. In addition, this transceiver supports various selectable multiple high-speed protocols and selectable spread spectrum clocking (SSC) up to 3.2Gbps.

In summary, the DS90UR910QSQX/NOPB serializer/deserializer is an ideal choice for low-power applications, including digital video transmission, external storage and memory interconnects, video over CAT-5E/6/7 applications, and HDMI cable extension. This device features a low-voltage differential signaling (LVDS) compatible output, selectable data rate (64 Mbps to 3.2 Gbps), selectable high-speed LVDS capable outputs, and adjustable pre-emphasis. In addition, it also provides various selectable multiple high-speed protocol modes, integrated equalizer, and selectable spread spectrum clocking (SSC) up to 3.2Gbps. Finally, this transceiver is designed for low power operations with a maximum power dissipation of 5 mW.
